Carbon Dioxide Capture and Sequestration . Unlike terrestrial, or biologic, sequestration, where carbon is stored via agricultural and forestry practices, geologic sequestration involves injecting carbon dioxide deep underground where it stays permanently. Learn More. EPA's Greenhouse Gas Reporting Program (GHGRP) collects information from facilities in 4. GHGs, suppliers of certain fossil fuels, and facilities that inject CO2 underground. EPA's Proposed Carbon Pollution Standards for New Power Plants. On September 2. 0, 2. U. S. Environmental Protection Agency announced a first step under President Obama's Climate Action Plan to reduce carbon pollution from power plants.

EPA is proposing carbon pollution standards for new power plants built in the future. Carbon capture and sequestration is one of the technologies new power plants can employ to meet the standard. Learn more about the proposed standards. Carbon dioxide (CO2) capture and sequestration (CCS) is a set of technologies that can greatly reduce CO2 emissions from new and existing coal- and gas- fired power plants and large industrial sources. CCS is a three- step process that includes: Capture of CO2 from power plants or industrial processes.
Transport of the captured and compressed CO2 (usually in pipelines). Underground injection and geologic sequestration (also referred to as storage) of the CO2 into deep underground rock formations.
These formations are often a mile or more beneath the surface and consist of porous rock that holds the CO2. Overlying these formations are impermeable, non- porous layers of rock that trap the CO2 and prevent it from migrating upward. The figure below illustrates the general CCS process and shows a typical depth at which CO2 would be injected. Watch the following videos to learn more about how CCS works: CCS Schematic (Subsurface depth to scale, 5,2. Why is it important? Carbon dioxide (CO2) capture and sequestration (CCS) could play an important role in reducing greenhouse gas emissions, while enabling low- carbon electricity generation from power plants.
As estimated in the U. S. Inventory of Greenhouse Gas Emissions and Sinks, more than 4. CO2 emissions in the United States are from electric power generation. CCS technologies are currently available and can dramatically reduce (by 8.
CO2 emissions from power plants that burn fossil fuels. Applied to a 5. 00 MW coal- fired power plant, which emits roughly 3 million tons of CO2 per year.
Conference: National Conference on Carbon Sequestration, Washington DC, (United States), 15-; Related Information: Presentation given at the First National. Carbon dioxide (CO2) capture and sequestration (CCS), also known as carbon capture and storage, is a set of technologies that can greatly reduce CO2 emissions. Carbon Capture and Sequestration (CCS), also known as carbon capture and storage, is a potential means to reduce greenhouse gas (GHG) emissions and.
EPA's Greenhouse Gas Reporting Program includes facilities that capture CO2 for the purpose of supplying the CO2 to the economy or for injecting it underground (Subpart PP). According to the Greenhouse Gas Reporting Program, CO2 capture is currently occurring at over 1. United States, mainly on industrial processes, and the CO2 is used for a wide range of end uses. End uses of CO2 include enhanced oil recovery (EOR), food and beverage manufacturing, pulp and paper manufacturing, and metal fabrication. The figure below shows the portion of CO2 that is currently being captured from power plants and other industrial facilities and the portion that is extracted by production wells from natural CO2 bearing formations in the United States. The second figure shows the various domestic end uses of captured and extracted CO2. As CCS becomes more widespread, it is expected that the portion of CO2 captured in the United States from power generation and industrial processes will increase.

Where can captured carbon dioxide be stored? After capture, carbon dioxide (CO2) is compressed and then transported to a site where it is injected underground for permanent storage (also known as . CO2 is commonly transported by pipeline, but it can also be transported by train, truck, or ship. Geologic formations suitable for sequestration include depleted oil and gas fields, deep coal seams, and saline formations. Department of Energy estimates that anywhere from 1,8. CO2 could be stored underground in the United States.
Department of Energy, NATCARB) Potential sequestration sites must undergo appropriate site characterization to ensure that the site can safely and securely store CO2. After being transported to the sequestration site, the compressed CO2 is injected deep underground into solid, but porous rock, such as sandstone, shale, dolomite, basalt, or deep coal seams. Suitable formations for CO2 sequestration are located under one or more layers of cap rock, which trap the CO2 and prevent upward migration. These sites are then rigorously monitored to ensure that the CO2 remains permanently underground.
The safety and security of CO2 geologic sequestration is a priority for EPA.
